There are too many of them, and amount of quests (that get very repeating and boring very quickly) is just staggering after you have completed 2 or 3 credos.
As a solution: amount of credo quests that you have to complete, should reduce over time, or something.
Current system is just way too tedious and grindy and overall shitty, because it limits your access to content of the game way too much.
Game already feels like another life that you must pour 100% of the time that you are awake on to do any progression.
You keep adding these fucking grindy mechanics, that you can basically do infinite amount and get infinite benefit.
Back in the days you could farm your fields, feed animals etc. and then be done for the grind and do something else.
But now there is infinite amount of grind with credos especially, that never stops. Or well, maybe after you have them all. But that takes a long time.
What is point of having like 20 credos If I can only get 2 of them?
